Have been trying to get a gallery to work with Radiant. I’ve tried the ‘Galleries’ extension - but could see no way to add images from the asset list to the gallery. Am also now looking at the Library extension and their fork of Paperclipped - but after trying to run the rake development db:migrate:extensions task - I’m now getting an error which says… undefined method `is\_taggable’ for #Class:0xb6d096f0 …nor can I start the webserver. Any ideas? Help? Tony ---

Pointing us to a specific repository would be helpful. Are you sure you have the latest versions of these extensions? Or is it possible that you have a version of Radiant that doesn’t work with a particular version of an extension? Often developers will tag versions of their extensions on [github.com](http://github.com) for older versions of Radiant. Does the rake task work when your extensions are not in vendor/extensions? (just move them out, try it, and move them back in) Or is there some combination of extensions which causes the error? For example, 1 extension might add features to another, but they are loaded in the wrong order. Extensions are loaded alphabetically (like plugins) but you can specify their load order in config/environment.rb If you have Library and Paperclipped, it’s likely that Library is loaded first and should not be. Try setting “config.extensions = [:paperclipped, :library, :all]” and adjust that as you need. ---

The library relies a variant of paperclip that I’ve been meaning for months to pull into the mainstream: [GitHub - spanner/paperclipped: Radiant extension for managing assets and images with the Paperclip plugin · GitHub](https://github.com/spanner/paperclipped) However, in this case I think the problem is a missing ‘taggable’ extension: [GitHub - spanner/radiant-taggable-extension: This is another tagging solution for radiant: more versatile but less to the point than the tags extension. · GitHub](https://github.com/spanner/radiant-taggable-extension) I’ve updated all these extensions to take out the (deprecated) config.extension hooks but right now that means dependencies aren’t properly caught and it’s easy to miss something. Sorry about the hassle: everything will work when we standardise on gems but until then it’s a bit in-between. (You could try installing all this from gems, but there are complications there too because at the moment most of my extensions are waiting in beta versions for the configuration interface to make it into radiant. The gems currently available are the beta versions and not compatible with radiant 0.9.1, or indeed with radiant edge. You would need the ‘preconfiguration’ branch.) As it happens I’ve just been updating an image gallery that uses exactly this combination: [http://lordmayorshow.org/library/history/](http://lordmayorshow.org/library/history/) So if there’s anything I can do to help, do let me know. best, will ---
